This workshop consists of four hands-on labs that take you from deploying a two-tier LAMP stack application in a single Lightsail instance to having a fully fault tolerant and scalable version of that same application.
Specifically, the four labs cover:
Creating the infrastructure you will use in the subsequent labs
Deploying a two-tier LAMP stack application as a monolith in a single Lightsail instance
Rearchitecting the application by separating the front-end from the database
Scaling and load balancing the web front-end.
